hepatic arterial infusion combined with lenvatinib and camrelizumab for unresectable hepatocellular carcinoma

Conditions: Hepatocellular Carcinoma

Summary: the purpose of this study is to evaluate the efficacy and safety of hepatic arterial infusion chemotherapy of oxaliplatin and raltitrexed plus lenvatinib and camrelizumab in patients with unresectable hepatocellular carcinoma (hcc).

hepatic arterial infusion chemotherapy (haic) of oxaliplatin and raltitrexed was effective and safe for hepatocellular carcinoma. lenvatinib was non-inferior to sorafenib in overall survival in untreated advanced hepatocellular carcinoma, and programmed cell death protein-1 (pd-1) antibody was effective and tolerable in patients with advanced hepatocellular carcinoma. no study has evaluated haic of oxaliplatin and raltitrexed plus lenvatinib and camrelizumab. thus, the investigators carried out this prospective, single-arm study to find out it.
